Livingston, 26, was 6-2 with a 3.62 earned-run average this season in 13 appearances (12 starts) for the Double-A Bowie Baysox. The clause in his contract allowed him to ask for his release if he wasn't on the major league roster by July 1. Livingston last appeared in "the bigs" with the Reds in 2007, and holds a 6.31 career ERA in just over 56 major league innings.
